假装钢琴 · Pretend Piano — Support
Device requirements
An iPhone with iOS 18 or later, paired with Apple Watch running watchOS 11 or later. Supported watches: Series 6 or later, SE (2nd generation) or later, and all Ultra models. Series 4, Series 5 and SE (1st generation) are not supported. Newer watchOS versions may require a newer iPhone system. Motion performance runs on the watch; iPhone edits and sends songs.
Install the watch app
Open Watch on iPhone → My Watch → Available Apps, then install Pretend Piano. Installation can take time. Keep devices nearby and connected; avoid repeatedly tapping Install.
No sound or gesture response
Start playing, check watch volume and audio output, then adjust sensitivity. Recalibrate guitar direction if needed. Use gentle movements and taps.
Headphone delay
Bluetooth audio may add noticeable delay. Try the watch speaker and check system audio settings.
A song has not arrived
Keep devices nearby and open both apps. Wait for save confirmation after sending. Reconnect and resend if needed; make room if the song list is full.
Photo recognition
Use clear printed numbered notation, one or two lines at a time, photographed straight on in even light. Use screenshots for notation on a screen. Check and edit the result; handwriting and complex layouts may not work reliably.
Deletion and backups
Deletion on the watch may wait for reconnection. Some upgrades retain local historical song backups without a backup-management interface. See the privacy policy.
